PK2300 108 s Sinking vs. Sourcing Drivers
The PK2300 has up to eight high-current driver outputs that can be
configured as “sourcing” or “sinking.” The configuration is selected by
installing the appropriate driver IC and by setting header H1. The factory-
installed driver chip and default jumper settings are for “sinking” control
(ULN2803).
Figure D-1 shows the locations of the driver ICs at U1 and U2. Figure D-2
shows the jumper configurations on header H1.
